Belladonna (West Saruta. [S]) spawns at the near-direct bottom right-hand corner G-7 (up on the ledge) with a spawn window of what appears to be an hour and a half, to two and a half hours (no placeholder).
Drop rate, probably looking at about 30%~ without treasure hunter, or at least in my case I went 1/4.
Note, it spawns within the same 15' (provoke range) radius nearly every single time, incase someone's curious as to how far it can stretch out to; it'll always be within eyesight, simply.
Will never replace haste belts for TPing, but it's the new best ACC belt for weaponskills. If you don't have access to swift or Vbelt, it's pretty excellent for TPing as well.
effective upgrade from Life Belt or Muscle Belt if you dont mind losing the +STR from muscle. most cases Swift still better but def something to look for if you are low on ACC.
This guy is better for tping than any haste belt while leveling to 75. I mean this because it's very hard to reach accuracy cap otw to 75 and there aren't many options for haste on equip until 72 for most jobs. Even a sam with hasso+kyahan+haste spell will find this belt better than swift.
Certainly though, one should be prepared for different exp setups. If undercamping (like 59-60 @ lesser colibri), which can mean good acc, and/or you get a brd singing marches a haste belt will start to shine.
A good dd should decide on demand which is better. There is nothing like a perfect solution.
